Does anybody know a way of either converting (on android) a putty key to something I can use in ConnectBot, or a good android SSH app that can use Putty keys natively?

I am away from home without my laptop, which I would usually use. I only have my android phone with me.

A few months ago I tried creating RSA key pairs to use with Putty on my laptop and ConnectBot but for some reason I just could not crack it so gave up. I also used puttygen to create an RSA key but it would not work on ConnectBot
